I had a SSgt who was on embassy duty a few yrs ago and said he often carried a .357 revolver. This was before I got into handguns so I didn't ask at the time. when on ship, I've seen the SEALS cleaning and if memory serves me correctly, I saw 1-2 lil back up revolvers here and there. Revolvers are few and far between in Military/LE unless used as a backup..
